IMPROVEMENT IN OIL-EJECTING CUPS.

Specification forming part of Letters Patent No. 50,183, dated September 26, 1865.

To all whom 'it may concern:

Be it known that I, HENRY E. STAGER, ot' Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and purposes and are provided with an elastic bot-A tom for ejecting the oil from the can.

rlhe invention consists in the employment or use of a wire or rod attached to the elastic bottom and extending; through the spout or nozzle for the purpose of preventing the clogging or choking up of the same.

The invention also consistsin the application of a valve to the rod to regulate the tlow ordischarge of oil from the can.

A represents the bodyof the can, which may be constructed of sheet metal as usual; and B is the elastic or spring bottom, also constructed and applied in the ordinary or any proper manner.

U represents the spout or nozzle, which is screwed into the upper end of the body A; and' D is a wire or rod, which is attached centrally to the bottom B, and extends upward and through the spout or nozzle 0,'the endot' the rod reaching nearly to the oriee of C when the bottom B is not pressed inward, as shown in the drawing. 'lhis wire or rod D being attached to the bottom B, of course moves with it whenever the bottom is actuated to eject the oil from the can, and said wire or rod effectually prevents the choking or clogging up ofthe spout or nozzle by foreign substances contained in the oil.

'On the wire or rod D, within the spout or nozzle, a screw-thread is ent, on which a cylindrical piece of wood, metal, or other material, E, is fitted to serve asavalve and regulate the discharge of oil from the can. This valvemay be screwed up and down on the wire or rod D, and as the spout or nozzle C is of conical t'oim, as usual, internally as well as externally, it will be seen that the flow of oil may be checked by screwing up the valve, and promoted by lowering it or screwing it down. This valve is an important feature of the invention, for oil varies considerably in density,son1e beingheavy and flowing slnggishly, and others light andY rare, tlowing freely. By means ofthe valve the How may be regulated as desired, whateverthe character of the oil may be.

-The end of the spout or nozzle G is expanded inbell form, as shown at a, leaving' a semispherical cavity, d, at its terminus, as shown clearlyinthedrawing. Thiscavity d prevents the drip or drop of oil at the end ofthe spout, which is left each time after the can is used, from passing down on the outer side of the can. The drop, when the can is placed in an upright position after use, will return into the cavity and descend down the nozzle. By this simple means the exterior of the can is kept comparatively clean or free from oil.l

I claim as new and desire to secure by Letters Patent- The adj ustable valve E,in combination with,lv

the thread on the rod D and the conical spout C to regulate the aperture. Y HENRY E. STAGEB.
